Penny: I mean really, what's so great about being grown up?
Bernadette: Well for starters, we'd be splitting this check three ways.

Bernadette: I had a plan. I kept leaving Dove bar wrappers around to explain any weight gain.
Amy: Where did you get empty Dove bar wrappers?
Bernadette: From all the Dove bars I ate! I'm pregnant! Try to keep up!

Stuart: Oh, so she's good enough for Howard but not for me?
Howard: Yeah.
Bernadette: Yeah. Go have weird relationships with your own mother and cousin. This is his turf.

Leonard: You don't go into science for the money.
Bernadette: Speak for yourself. Last month my company both invented and cured restless eye syndrome. Ka-ching, ya blinky chumps!

James Earl Jones: Let me guess. You like Star Wars.
*Sheldon nods*
James Earl Jones: You know I've been in other movies.
*Sheldon nods*
James Earl Jones: But you don't care about those, do you?
*Sheldon shakes his head*
*James Earl Jones signals for Sheldon to come closer*
James Earl Jones: I have one thing to say to people like you. I like Star Wars too! Care to join me?

Amy: Why can't they do something sensible like Sheldon, and start their own comic book convention? Also, who wants to throw me out that window?

Bernadette: Well, while they're acting like teenagers we could do something grown up.
Amy: Ooh, you mean like a museum?
Penny: Yes, like a museum but anything else!
